'What the hell's the matter with you?' Joe Biden blames GOP reps who refused to wear masks in Capitol safe room for giving COVID to four Democrats including a cancer survivor

President-elect Joe Biden tore into the group of Republican lawmakers who refused to wear masks as the Capitol was being mobbed last week.

'It was shocking to see members of Congress, while the Capitol was under siege by a deadly mob of thugs, refusing to wear a mask while they were in a secure location,' Biden said Friday in Wilmington. 

'What the hell is the matter with them?' the incoming president asked. 'Time to grow up.'

'The result?' Biden continued. 'At least four members of Congress today, including a cancer survivor, now have COVID-19 who were in those rooms.'

'For God's sake,' Biden added. 

He also scoffed at President Donald Trump turning mask-wearing into a politicized issue.

'What a stupid, stupid thing for it to happen,' Biden commented.

And he applauded the efforts of his home state congresswoman, Rep. Lisa Blunt Rochester, who was seen in footage from that day trying to hand out masks to a group that included 'QAnon' Rep. Marjorie Taylor Greene.

Taylor Green was among the mask-refusing Republicans who are being blamed for the COVID infections of Democratic reps Bonnie Watson Coleman - a 75-year-old cancer survivor - Adriano Espaillat, Pramila Jayapal and Brian Schneider.

Appalled: Joe Biden slammed Republicans who refused to wear masks while House members were sheltering in a safe room as the MAGA mob ran rampant

House lawmakers who were whisked to safety when a violent mob of Donald Trump supporters stormed the Capitol were filmed bickering over masks as they hunkered down in a safe room

Video from inside the room, obtained by Punchbowl News, showed several Republican lawmakers not wearing masks - including Reps Andy Biggs , Michael Cloud , Taylor Greene , Markwayne Mullin and Scott Perry .    

Rochester, who was walking around handing out masks, repeatedly asked those in the maskless group to take one, but they brushed her aside. 

'I’m not trying to get political, in fact, I just want to get along but I appreciate you,' Mullin was heard to say.

Democrats have implemented $1,000 a day fines on lawmakers who refuse to wear masks while in the Capitol complex.     

Espaillat on Thursday said he had tested positive for COVID-19, becoming the fourth member of Congress to announce they had contracted the coronavirus following a mob attack on the U.S. Capitol last week.

'I am following guidance from my physician and quarantining at home after having tested positive for COVID-19,' he wrote on Twitter.

The 66-year-old New York City Democrat said he received a second dose of coronavirus vaccine last week but noted that vaccinations take time to become effective.

'I have continued to be tested regularly, wear my mask and follow the recommended guidelines,' Espaillat wrote on Twitter. 'I will continue my duties representing New York's 13th congressional district remotely until I have received clearance from my doctor.'  

Rep. Pramila Jayapal has become the second Democratic congresswoman to test positive for COVID-19 after being forced to shelter in a secure room with maskless Republicans during last Wednesday's siege of the Capitol

Adriano Espaillat on Thursday said he had tested positive for COVID-19, becoming the fourth member of Congress to announce they had contracted the coronavirus following a mob attack on the U.S. Capitol last week.

Schnenider said Tuesday: 'Last Wednesday, after narrowly escaping a violent mob incited by the President of the United States to attack the Capitol and its occupants, I was forced to spend several hours in a secure but confined location with dozens of other Members of Congress.

'Several Republican lawmakers in the room adamantly refused to wear a mask... even when politely asked by their colleagues,' he continued, pointing to a video posted online by Punchbowl News showing that. 

He said he was in isolation and worried about exposing his wife to the disease. 

'Today, I am now in strict isolation, worried that I have risked my wife's health and angry at the selfishness and arrogance of the anti-maskers who put their own contempt and disregard for decency ahead of the health and safety of their colleagues and our staff,' Schneider said.

Jayapal announced late Monday night that she too had tested positive for COVID after sheltering in a small, poorly ventilated room with more than 100 lawmakers last week. 

She also blamed Republicans for her infection. 

'I just received a positive COVID-19 test result after being locked down in a secured room at the Capitol where several Republicans not only cruelly refused to wear a mask but recklessly mocked colleagues and staff who offered them one,' the 55-year-old posted.  

After her announcement, Republican Congresswoman Marjorie Taylor Greene, a hard-line Trump supporter who has expressed support for QAnon theories, took a shot back at Democrats.

'I hope you fully recover from #COVID19 without any complications!,' she said in a retweet of Jayapal's announcement. 'Before you point fingers at me or anyone else, you need to talk directly to @SpeakerPelosi about exposing ALL of us to covid when she called back POSITIVE covid House members last week for votes for Speaker!'

She was referring to a vote in the House last week attended by some Democrats who had previously  positive for COVID. Those lawmakers said they had consulted with the medical staff before attending the vote series.

Jayapal says she is convinced more positive test results will follow, claiming that being forced to huddle in the room will turn out to be 'a superspreader event'. 

On Monday afternoon, Coleman was the first to announce her positive diagnosis.
